BannerAd mines Bitcoins in your Browser

Adam Jogrady ist nach dem Laden einer Website mit einem Banner für 'ne Bitcoin-Börse aufgefallen, dass das Teil 40MB runtergeladen hatte und der CPU komplett ausgelastet war. Lösung: Das Banner rechnete im Hintergrund Bitcoins aus. Quite cyberpunk, this ad.

Ein paar Bits aus den Replies auf Twitter:

Noticed a site had downloaded 40MB+ and maxed CPU, checked sources and discovered it was a Bitcoin add in iframe, looked at JS it used.

At 100h/s, 5minute avg ad view, you need over 2 billion ad impressions/day to get 1GH/s = $0.48 a year. Even slightly annoying one potential customer by abusing their machine like this outweighs the expected returns of zero due to mining.
